The cause of injury is often a fall on an outstretched hand with an extended wrist, and in most cases there is a concomitant distal radius fracture. The aims of this retrospective study were to investigate the results of the current treatment of distal ulna fractures in adults, with or without a concomitant distal radius fracture, and if a recently presented fracture classification could predict outcome.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and methods<\/jats:title>\n                <jats:p>Patients, 18\u00a0years or older, treated for a fracture of the distal third of ulna in our county, were included. Fractures of the styloid tip were excluded. The radiographs of the fractures were independently classified by two specialists in radiology according to the 2018 AO\/OTA classification. Follow-up was performed 5\u20137\u00a0years after the injury, through the questionnaire Patient-Rated Wrist Evaluation (PRWE) and new radiographs of both wrists.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Ninety-six patients with 97 fractures were included and filled out the PRWE. 65 patients also had new radiographs taken. 79 patients were women and the mean age at the time of injury was 63\u00a0years (SD 14.5). The most common fracture class was the extra-articular transverse fracture, 2U3A2.3 (42%). We found that 40% of the fractures had been treated by internal fixation and only 2 fractures had not healed, one conservatively treated and one operated. The median PRWE was 15 (IQR 33.5). The PRWE score was significantly worse in the operated ulna fractures (<jats:italic>p<\/jats:italic>\u2009=\u20090.01) and this was also true for extra-articular transverse fractures 2U3A2.3 (<jats:italic>p<\/jats:italic>\u2009=\u20090.001). Initial displacement was more common in operated transverse fractures, but it could not be proven that this was the reason for the inferior result.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Distal ulna fractures almost always unite and the result is comparable to that of isolated distal radius fractures when measured by PRWE. Based on the opinions of the radiologists and how often a consensus discussion was needed for classification, we found the updated AO classification system difficult to use, if dependent only on standard radiographic views. In the present study, transverse extra-articular ulna fractures did not benefit from internal fixation regardless if associated with a distal radius fracture or isolated.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00402-022-04336-1","type":"journal-article","created":{"date-parts":[[2022,1,21]],"date-time":"2022-01-21T19:59:49Z","timestamp":1642795189000},"page":"381-387","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Distal ulna fractures in adults\u2014subcapitular, transverse fractures did not benefit from surgical treatment"],"prefix":"10.1007","volume":"143","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9341-6798","authenticated-orcid":false,"given":"Maria","family":"Moloney","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon","family":"Farnebo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Adolfsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,1,21]]},"reference":[{"issue":"4","key":"4336_CR1","doi-asserted-by":"publisher","first-page":"237","DOI":"10.1097\/BOT.0b013e31819b24e9","volume":"23","author":"R Arora","year":"2009","unstructured":"Arora R, Gabl M, Gschwentner M, Deml C, Krappinger D, Lutz M (2009) A comparative study of clinical and radiologic outcomes of unstable colles type distal radius fractures in patients older than 70 years: nonoperative treatment versus volar locking plating.
